DECORATIVE TABLE LAMP WITH ADJUSTABLE LIGHT DEFLECTOR Fild June 28, 1950 INVENTOR. LEE Slice/57 AT OE/VEY Patented Apr. 15, 1952 DECDRATIVE TABLE LAMP WITH ADJUST- ABLE LIGHT DEFLECTOR Lee Secrist, Euclid, Ohio, assignor to Phil-Mar Corporation, Cleveland, Ohio, a corporation of Ohio Application June 28, 1950, Serial No. 170,715

This invention relates to lamps and particularly to decorative table lamps.

The primary object of this invention is to provide a. lamp'that produces indirect light that may be selectively deflected in a plurality of directions.

Another object is to provide a lamp of the type stated that can be adjusted to deflect light either directly downward or to one side.

A further object is to provide a lamp structure that will remain relatively cool even though a concealed incandescent electric bulb is contained in the lamp body.

Still another object is to provide a lamp that is rugged in structure, attractive in appearance and economical to manufacture.

These and other objects of the invention will become apparent from a reading of the following claims and specification, together with the accompanying drawing, wherein like parts are referred to and indicated by like reference characters and wherein:

Figure 1 is a front elevation of the lamp with parts broken away to show the inner structure;

Figure 2 is a top plan view of the spider;

Figure 3 is a side view of the same;

Figure 4 is a bottom View of the same;

Figure 5 is a side elevation of the reflector;

Figure 6 is a top view of the reflector taken along the line and in the direction of the arrows 6-6 of the Figure 5;

Figure 7 is a plan View of the reflector blank, and

Figure 8 is a top view of a portion of the deflector.

Referring to the drawing there is shown in the Figure l, a table lamp made in accordance with this invention. The device consists broadly of four elements or members; the body, the reflector, the spider and the deflector. Each of these members is broadly indicated by the reference numerals it, 20, 39 and 48 respectively and will be disclosed in detail in the order stated.

The body 10, which is hollow, is made in the shape of an inverted frustum of a cone having an open top IT. The body Ill of the lamp illustrated in theFigure 1 is positioned on a subbase H which serves as an added decorative feature but is not necessary to the practice of this invention. I

3 Claims. (01. 240-431) The lamp body it is made of pottery or other suitable material which is opaque and may have its exterior embellished by color or a textured finish. The sides of the body are straight and at an angle to the vertical center line of the body.

A hollow center post l2 which supports an electric socket I3 is positioned within the body as shown. A switch handle I4 for operating the socket protrudes through a hole bored or otherwise formed in the side of the body member. An incandescent electric bulb is seated in the socket entirely within the body and below its open top H. Electric current is carried to the bulb by means of the cable I6 which travels through the hollow post l2 into the socket l3.

Reference numeral Zll indicates a frusto-conically shaped metal shell or reflector that is shaped to wedgedly seat within the body member.

The lower diameter 22 of the reflector is greater than the lower'end of the body l0 so that the reflector will position itself opposite the region of the bulb I5 when placed into the body as shown in the Figure l.

The reflector 20 is preferably made of brightly polished non-corrosive metal such as aluminum cut from a flat sheet to the form shown in the Figure '7. The blanked reflector has curved upper and lower edges 2| and 22 respectively. The lower edge 22 has a notch 23 cut therein for the passage of the switch handle Id. The blank is folded until its sides meet to form the frustoconical reflector 2!) shown in the Figures 1, 5 and 6.

The aforementioned spider or frame 30 is made of wire of a suitable gage and is shaped as shown in detail in the Figures 2, 3 and 4. Reference numerals 34 and 32 designate upper and lower rings respectively which are both spaced apart and supported by three arms 33. The arms extend radially from the upper ring 34 and then are turned downward at an angle matching that of. The combined size and shape of the rings and arms of the spider is such that the spider will interfit the interior of the body in a wedge fit when placed within the body as shown in the Figure 1. In order to accomplish this the overall length of both the reflector 20 and the spider 38 is made less than the length of the body H3.

The upper ring 34 acts as a support for the post 35 which extends vertically therefrom. A ball and socket joint 36 having friction means therein to prevent its free motion is positioned at the top end of the post 35.

Reference numeral 40 indicates a circular disk shaped deflector mounted at its center 4| on the ball and socket joint 36. The deflector 40 is secured in place by a decorative finial 31.

The deflector is made approximately three and one-half to four times the diameter of the open upper end I! of the lamp body. A wire ring 44 forms a frame to which two disks 4'2 and 43 of pressed fiber glass are attached. The lower disk 43 is made of white pressed fiber glass and provides a translucent light difiusing surface. The upper disk is made of colored pressed fiber glass.

In assembling the lamp the reflector 20 is positioned within the body Ill and the spider is in turn nested within the reflector as shown in the Figure l. The matching configuration of the frusto-conical body, reflector and spider causes them to wedge themselves into one rigid unit to which the deflector 46 is tiltably attached by means of the ball joint 36 as described hereinbefore.

The reflector 20 which entirely surrounds the incandescent bulb l reflects not, only the light but also the heat generated by the bulb upward and through the open end I! of the body Ill. The outer surface of the lamp body therefore remains cool to the touch even though the bulb I5 is entirely within the body.

The light reflected from the reflector 20 is impinged upon the under surface 43 of the deflector disk 40 from which it is deflected directly downward upon the surface upon which the lamp is standing when the deflector is in a horizontal position as shown in the Figure 1. When the deflector is tilted to the position designated by the reference numerals 40a, Mb, Mo and 48d, light from the reflector 2:3 is deflected in the direction in which the lower surface of the disk 40 is faced. A small percentage of the light passes through the lower surface 43 to import a colored decorative glow to the colored upper surface 42.

The lamp just described is particularly intended for horizontal surface illumination as well as being adapted to deflect light upon a side wall while at the same time protecting objects on the lee side of the deflector 40 from illumination.

A lamp constructed in the manner just described is particularly suited for providing subdued illumination in rooms where television sets are in operation. The large surface area of the fiber glass deflector 40 both diffuses and deflects the light over a broad area so that glareless illumination is provided.

It will now be clear that there has been provided a device that accomplishes the objectives heretofore set forth. While the invention has been disclosed in its preferred form, it is to be understood that the specific embodiment thereof as described and illustrated herein is not to be considered in a limited sense as there may be other forms or modifications of the invention which should also be construed to come within the scope of the appended claims.
